dc.description.abstractIn the present work, ultrathin PtxCo1-x (x=1, 0.75, 0.5 and 0.25) alloy films are fabricated using co-sputtering with approximately 2nm in thickness. The stoichiometry and structural characterization of the thin films are obtained from SEM, EDX and XPS measurements. The structural characterization of the thin films showed smooth coverage of the surface, in a fcc crystalline plane (111). The resistive properties of the films are tested towards a hydrogen gas sensor between 25 °C - 150 °C in the gas concentration ranging from 0.5% to 5%. The surface scattering phenomenon could explain the hydrogen gas sensing mechanism of ultrathin PtxCo1-x alloy thin films. PtCo alloy thin films show better response time than bare Pt thin films. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2. All rights reserved.en_US
